Radu Gheorghe commented on SOLR-11473: -------------------------------------- Sounds good, thanks Uwe! Should I just attach a patch with that change? > Make HDFSDirectoryFactory support other prefixes (besides hdfs:/) > ----------------------------------------------------------------- > > Key: SOLR-11473 > URL: https://issues.apache.org/jira/browse/SOLR-11473 > Project: Solr > Issue Type: Improvement > Security Level: Public(Default Security Level. Issues are Public) > Components: hdfs > Affects Versions: 6.6.1 > Reporter: Radu Gheorghe > Priority: Minor > > Not sure if it's a bug or a missing feature :) I'm trying to make Solr work > on Alluxio, as described by [~thelabdude] in > https://www.slideshare.net/thelabdude/running-solr-in-the-cloud-at-memory-speed-with-alluxio/1 > The problem I'm facing here is with autoAddReplicas. If I have > replicationFactor=1 and the node with that replica dies, the node taking over > incorrectly assigns the data directory. For example: > before > {code}"dataDir":"alluxio://localhost:19998/solr/test/",{code} > after > {code}"dataDir":"alluxio://localhost:19998/solr/test/core_node1/alluxio://localhost:19998/solr/test/",{code} > The same happens for ulogDir. Apparently, this has to do with this bit from > HDFSDirectoryFactory: > {code} public boolean isAbsolute(String path) { > return path.startsWith("hdfs:/"); > }{code} > If I add "alluxio:/" in there, the paths are correct and the index is > recovered. > I see a few options here: > * add "alluxio:/" to the list there > * add a regular expression in the lines of \[a-z]*:/ I hope that's not too > expensive, I'm not sure how often this method is called > * don't do anything and expect alluxio to work with an "hdfs:/" path? I > actually tried that and didn't manage to make it work > * have a different DirectoryFactory or something else? > What do you think? -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
